Editor’s note: Cosmetics & Toiletries is pleased to revive its former “Testing Tactics” column with two new columnists. Chris McLeod will focus on skin beginning in June 2013, and Trefor Evans, PhD, featured here, focuses on hair. Evans’ expertise in designing tests and interpreting results will advance the scientific understanding of hair and strengthen claims substantiation. Readers are invited to engage in this article on the Cosmetics & Toiletries' LinkedIn Group, or send comments to CTEdit@allured.com.
